To pack is to fill a container or bag with things, or to press things closely together.
From Middle Low German *pak* “bundle, package,” related to trade and shipping. It first referred to bundled goods and later to the action of filling and arranging them.
Packing is like solving a 3‑D puzzle: you’re trying to fit shapes, weight, and priorities into limited space. How someone packs often reveals their personality—minimalist, ‘just in case’ person, or chaotic last‑minute stuffer.
